A recognizer structure is an application for forming or using a rectitor that is used as a marker for entering a predetermined part of an animal (or a plant or other object), and is capable of being positioned by a simple operation. The material is formed into a wide strip-shaped labeling member. In the middle section of the marking member, a support portion is held, and a side of the supporting portion is formed with a flexible turning portion, so that the marking member can be adapted. In the opposite direction, at one end of the aforementioned marking member, a restriction passage is combined to allow a section of the insertion portion formed at the other end of the indicator member to be introduced into the center hole along the guide groove of the restriction passage and a slight external force when the folding portion is folded. And the surface of the indicator member facing outward is marked with a mark； as the identifier, the inside of the identifier is used to correspond to the pre-marked portion, and then the end portion of the end portion is slightly biased to penetrate the pre-marked portion and the restricted portion. Hole, you can complete the orientation limit of the recognizer.一種識別器結構，是對用在打入動物預設部位(或植物、其他物件)作為標記的識別器在構件成形或使用能藉簡易操作即可獲有定位的應用，是採在：以預設材質成形合宜寬幅的條狀標示件，在標示件的中間段落是保持一支持部、及在支持部相鄰一側是形成一截具撓性的轉折部，以利標示件可作適切對折，在前述標示件的一端是結合一限制段落，以允許標示件另端形成的一截啣入段落可在對折時沿著限制段落其導溝並稍施一外力使順勢引入中心的孔，及前述標示件朝外一側層面是記載入標記；作為識別器在使用可內側對應著預作標記部位抵靠、再將一端的啣入段落稍施外力使貫穿預作標記部位及限制段落的孔，即可完成識別器的方位限制。
